Neural Networks Fundamentals: Neurons and Layers in R

Overzicht

This course introduces the core building blocks of neural networks. You'll learn what a neuron is, how it processes information, the role of activation functions, and how neurons are organized into layers.

By the end, you'll implement a single dense layer from scratch using R and base R matrix operations.
